In the acceleration phase you get one set of issues created by the leverage. In the decel phase you get a whole new set of issues, like how do you keep a joint from separating while decelerating the object on the end of the leverâŚie, the hand. The throwing motion is all about the creation of leverage and the shedding of leverage. The physics are simple â the more weight you put in your hand the more leverage you create. We often see kids in a pitching clinic going through the throwing motion with a towel in their hand. Ugh. We understand what they âthinkâ they are accomplishing but realize what they are âactually doingâ. (ie, leveraging up the acceleration phase with resistance â the towel â while increasing the weight -the towel- the weakest joint has to endure in slowing the added weight- the towel- down. Normally this weight in the decel phase would have been shedded with the release of the ball.)
